Quality Control and Correction of Temperature Wellhole Data in the Southern North Sea

P281 QUALITY CONTROL AND CORRECTION OF TEMPERATURE WELLHOLE DATA IN THE SOUTHERN NORTH SEA. Summary 1 A reliable temperature database including an effective quality coding is important for carrying out geothermal and maturity studies. This paper discusses the results of a quality control and correction of temperature measurements from released wells in offshore Netherlands. The correction procedure starts with the selection of a reference data set representative for the virgin rock temperature. This reference data set is selected from the drillstem test temperatures (TDST) based on their reliability. Subsequently an empirical correction function is derived for correcting Horner extrapolated bottom-hole
